And you say, "Why is it?"-- Because the LORD is witness between you and the wife of your youth, With whom you have broken faith though she is your companion, your betrothed wife. Did he not make one being, with flesh and spirit: and what does that one require but godly offspring? You must then safeguard life that is your own, and not break faith with the wife of your youth. For I hate divorce, says the LORD, the God of Israel, And covering one's garment with injustice, says the LORD of hosts; You must then safeguard life that is your own, and not break faith.
Malachi 2:14-16
You have defied me in word, says the LORD, yet you ask, "What have we spoken against you?" You have said, "It is vain to serve God, and what do we profit by keeping his command, And going about in penitential dress in awe of the LORD of hosts? Rather must we call the proud blessed; for indeed evildoers prosper, and even tempt God with impunity."
Then they who fear the LORD spoke with one another, and the LORD listened attentively; And a record book was written before him of those who fear the LORD and trust in his name. And they shall be mine, says the LORD of hosts, my own special possession, on the day I take action. And I will have compassion on them, as a man has compassion on his son who serves him. Then you will again see the distinction between the just and the wicked; Between him who serves God, and him who does not serve him.
Malachi 3:13-18
